[jira] [Created] (SPARK-15838) CACHE TABLE AS SELECT should not replace the existing Temp Table

Xiao Li created SPARK-15838:
-------------------------------

             Summary: CACHE TABLE AS SELECT should not replace the existing Temp Table
                 Key: SPARK-15838
                 URL: https://issues.apache.org/jira/browse/SPARK-15838
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.0.0
            Reporter: Xiao Li


Currently, {{CACHE TABLE AS SELECT}} replaces the existing Temp Table, if existed. This behavior is different from `CREATE TABLE` or `CREATE VIEW`. It looks risky.
